MVS governor is equipped with high speed and low speed limit screw to limit the limit position of speed control handle.


When the speed control handle of the PT pump is in a certain position, the double arms lever under it will balance the elastic force of the MVS speed control spring with the oil pressure on the left side of the plunger, so that the generator set can work stably at this speed.


When the load of the diesel engine decreases and the engine speed increases, the oil pressure on the left side of the plunger increases. As a result, the plunger moves to the right and the diesel channel from the throttle is closed, reducing the output oil pressure of the PT pump and reducing the circulating oil injection amount of the fuel pump to limit the increase of the generator speed.


On the contrary, when the generator set's load increases and its speed decreases, the spring's spring force is greater than the oil pressure on the left side of the plunger. The plunger moves to the left and the diesel channel from the throttle valve is opened wider, which increases the output oil pressure of the PT pump and increases the circulating oil injection amount of the fuel pump to limit the decline of the generator set's speed.
